NAME
glPushClientAttrib - push and pop the client attribute stack
C SPECIFICATION
void glPushClientAttrib(GLbitfield mask);
PARAMETERS
mask
Specifies a mask that indicates which attributes to save. Values
for mask are listed below.
C SPECIFICATION
void glPopClientAttrib(void);
DESCRIPTION
glPushClientAttrib takes one argument, a mask that indicates which
groups of client-state variables to save on the client attribute stack.
Symbolic constants are used to set bits in the mask. mask is typically
constructed by specifying the bitwise-or of several of these constants
together. The special mask GL_CLIENT_ALL_ATTRIB_BITS can be used to
save all stackable client state.
The symbolic mask constants and their associated GL client state are as
follows (the second column lists which attributes are saved):
GL_CLIENT_PIXEL_STORE_BIT Pixel storage modes
GL_CLIENT_VERTEX_ARRAY_BIT Vertex arrays (and enables)
glPopClientAttrib() restores the values of the client-state variables
saved with the last glPushClientAttrib. Those not saved are left
unchanged.
It is an error to push attributes onto a full client attribute stack or
to pop attributes off an empty stack. In either case, the error flag is
set, and no other change is made to GL state.
Initially, the client attribute stack is empty.
NOTES
glPushClientAttrib is available only if the GL version is 1.1 or
greater.
Not all values for GL client state can be saved on the attribute stack.
For example, select and feedback state cannot be saved.
The depth of the attribute stack depends on the implementation, but it
must be at least 16.
Use glPushAttrib() and glPopAttrib() to push and restore state that is
kept on the server. Only pixel storage modes and vertex array state may
be pushed and popped with glPushClientAttrib and glPopClientAttrib().
For OpenGL versions 1.3 and greater, or when the ARB_multitexture
extension is supported, pushing and popping client vertex array state
applies to all supported texture units, and the active client texture
state.
ERRORS
GL_STACK_OVERFLOW is generated if glPushClientAttrib is called while
the attribute stack is full.
GL_STACK_UNDERFLOW is generated if glPopClientAttrib() is called while
the attribute stack is empty.
ASSOCIATED GETS
glGet() with argument GL_ATTRIB_STACK_DEPTH
glGet() with argument GL_MAX_CLIENT_ATTRIB_STACK_DEPTH
